WRENCH.

SPECIFICATION forming part of Letters Patent LTO/189,605, dated January10, 1893.

Application led April 23, 1892. Serial No. 430,398. (No model.)

.To all whom it may concern:

Bev it known that I, SANFORD GAssER, a ctizen of the United States,residing at Trout Creek, in the county of Ontonagon and State ofMichigan, have invented a new and useful Wrench, of which the followingis a specification.

My invention relates to wrenches of that class employing and knownasslidingjaw.

The objects of my invention are to provide a wrench of great simplicityin construction and effectiveness in operation, whose capacity foroperating upon nuts, rods and pipes of various sizes is increased; thatmay be employed as a hammer in applying nails or rivets or withdrawingthe former; and to provide a simple and conveniently operated means foradj ustin g said sliding jaw with relation to the stationary j aw, andsecurely locking the same.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings:-Figure l represents a perspective view of awrench -constructed in accordance with my invention. Fig. 2 is avertical longitudinal section of the same. Fig. 3 is a detail of thelocking-block.

Like numerals of reference indicate like parts in all the figures of thedrawings.

l designates the shank or stock of the wrench, and the same isrectangular in crosssection, being provided at its lower end with asuitable handle, 2. Above the handle one edge of the stock is providedwith a series of teeth 3, which are inclined or upwardly disposed, asshown. The upper end of the stock is provided with a transverse head 4,forming at the front and rear sides of the shank jaws 5 and 6respectively. The outer face of the jaw 5 is inclined, and is bifurcatedor provided With a claw 6 for withdrawing nails. The inner face of thejaw 5 is flared with relation to the stock l, or in other words isinclined as shown, and has formed thereon a series of transverse teeth,which are inclined and disposed toward the extremity of the jaw. The jaw6 is also provided with teeth, inclined or inwardly disposed, as shown,and butvery little flared as compared with the jaw 5. The end of thehead 4, at which the jaw 6 is located, terminates in a hammer-face 7,which may be used to drive nails, rivets, or for other general purposes.

S designates the sliding-head, the same having a central rectangularbore 9, for the loose reception of the stock l. The head 9 extends toopposite sides of the stock, to form a second front jaw 5, and a secondrear jaw 6. The lower front jaw 5, or the one just mentioned, isprovided with a series of transverse teeth, oppositely disposed withrelation to those of the upper jaw 5, or in other words areinwardly-disposed, and the jaw 6 of the slidinghead is provided withteeth disposed oppositely to those of the upper jaw 6, or in other wordsoutwardly disposed.

A spring-metal strip 9, is secured to the front face of thesliding-head, and depends from the same, terminatingin anoutwardly-turned finger-hold or hook 10, and riveted to the inner sideof this strip is a ratchet-faced block ll, the teeth of which aredownwardly-dis- 'posed or in other words are contrarily disposed to theteeth 3 of the stock l. A iiat spring l2 is secured at 13 to the underside of the jaw 5, is bent to conform to the angular -portion of thejaw, and at its lower free end rests iiatly against the outer side ofthe strip, and serves to press the ratchetfaced block inwardly, so thatits teeth engage with those of the stock.

By reason of the divergence of the jaws 5 and 6, it will be seen thatthe former are adapted to operate upon pipes or rods of greater diameterthan they otherwise would be; and may be more readily applied thereto.The same is true as to the jaws 6, with relation to nutsA By graspingthe finger-hold of the spring-metal strip of the ratchet-faced block, itwill be seen that the latter may be drawn outwardly or out of engagementwith the teeth 3 of the stock of the wrench, again st the tension of theflat spring, and then the v head 8 slid down to any point along thestock,

or moved up upon the stock, as may be desired or in the upward movementof the head the ratchetfaced block need not be withdrawn from engagementwith the teeth of the stock, but said block will simply glide over thesaid teeth, engaging at any point thereof when the head is at rest. Bysuch an arrangement, accurate and rapid adjustments are attained withlittle or no eort upon the part IOO of the handler. It will be seen thatt-he iat spring will combine with the inner spring strip to maintain theblock in proper engagement, and that when said block is drawn away fromthe stock the spring will ride over the face of the strip.

Having described my invention, what I claim isz- 1. In a wrench of theclass described, the combination with the rectangular stock, terminatingat its lower end in a handle, and at its upper end in a head forming ajaw, of a sliding head mounted on the stock, and provided with a jawadapted to co-act with that of the head of the stock, a spring metalstrip secured to the sliding head at the front side thereof andextending below the same, a block secured to the underside of the stripand having a ratchet-face, the teeth of which are downwardly disposed ina direction contrary to a series of teeth formed on the face ot' thestock and a iiat metal spring secured to the sliding head and restingflatly against the metal strip, substantially as specified.

2. In a wrench, the combination with the rectangular stock provided witha series of teeth on its outer face, at its lower end provided with ahandle and at its upper end with a transverse head forming front andrear jaws, slightly diverged from the stock, the front jaw beingprovided with outwardly-disposed transverse cleats, the rear jaw withinwardly-disposed transverse cleats, the sliding head having a borefitting the stock and provided at opposite sides of the same with jaws,the front one having inwardly disposed teeth and the rear one havingoutwardly-disposed teeth, the spring-metal strip secured to the frontface of the sliding head, extending below the head and bent to form afinger-hold, the block 11 secured to the inner side of the same andhaving a ratchet face, and the fiat spring secured to the front face ofthe head and having its lower free end resting on the outer face of themetal strip, substantially as speciiied.

In testimony that I claim the foregoing as myown I have hereto affixedmy signature in the presence of two witnesses.

SANFORD GASSER.
